Many times!!! And if the thread was damaged you will find a nut has exactly the same probs!!!

It is a very common engineering process - can't believe nobody has heard of it!!!

That doesnt say anything about being able to unscrew them afterwards

EDIT : Ok yes it does - sorry I missed that on the first read through...

Have used it to sort out damaged threads in castings etc - use a metal filled epoxy and the threads are really strong.

Yeah I've done it too. I won't use silicone grease though. I hate the stuff-it makes everything around it unbearably slippery and never goes away.

A tiny bit of LM grease on the bolt works for me-I dip it in and wipe the excess off.

I think you caught em with their knickers down Codprawn! You're right!
You can coat the bolt and threads with some sort of release agent if you want to take it out again. Speaking of epoxy, Do you blokes have access to a product called Marine Tex over there? Truly great stuff, you can drill it, tap it, even fix cracks in engine blocks with it. Very popular here with people in the know.

I assume you mean epoxy putty? It's all the same no matter what make you get. I picked up a load from a local cheap shop called Hypervalue - £1 for 2 big sticks - bought about 10 packs - usually about £5 for a small amount!!!

When you are stuck you can make your own metal filled epoxy by using filings mixed with normal 24hr epoxy. Use the correct ones for the parent metal - ie alloy block use aluminium powder/filings etc.
